SS SPHERICAL DISC BUTTERFLY VALVE PTFE SEATED SS 316

Features of SS Spherical Disc Butterfly Valve (PTFE Seated, SS 316) : 

• Body Material – SS 316

  • Made from high-grade Stainless Steel 316, providing excellent resistance to corrosion, chemicals, and high-temperature media.

  • Ideal for aggressive and corrosive environments, including chemical and pharmaceutical industries.

• Spherical Disc Design

  • Precision-engineered spherical disc ensures uniform sealing and reduced wear on the seat.

  • Offers better flow control, lower torque operation, and improved shutoff performance.

• PTFE Seat (Teflon)

  • Fitted with a PTFE (Polytetrafluoroethylene) seat, providing outstanding chemical resistance and low friction.

  • Non-reactive and suitable for handling corrosive and high-purity fluids.

• Zero Leakage Shutoff

  • PTFE seat and spherical disc combination delivers bubble-tight sealing, even at low torques.

• Compact and Lightweight

  • Space-saving design compared to conventional valves.

  • Easier handling and installation, especially in compact pipelines or skids.

• Mounting Design – Wafer / Lug Type

  • Designed for wafer or lug-type mounting, suitable for sandwiching between flanges for quick and secure installation.

• Operation Options

  • Available with manual lever, gear operator, or automation-ready (pneumatic/electric actuators).

• Pressure and Temperature Rating

  • Designed to handle moderate to high pressures (typically PN10/PN16) and temperatures up to 180°C (may vary depending on seat and seal material).

• Low Torque Requirement

  • PTFE seat and smooth disc movement result in low operating torque, reducing actuator size and energy consumption.

• Corrosion & Contamination Resistance

• Suitable for food-grade, pharmaceutical, and chemical processes due to non-reactive SS 316 + PTFE combination.

• Easy Maintenance

• Seat and disc can be accessed and replaced without removing the entire valve from the pipeline.

• Fewer moving parts reduce wear and maintenance downtime.

Application of uses :

• Chemical Processing Plants

  • Ideal for handling corrosive and reactive chemicals such as acids, solvents, and alkalis due to PTFE seat and SS 316 construction.

• Pharmaceutical Industry

  • Suitable for hygienic applications and cleanroom environments where contamination resistance and easy cleaning are essential.

• Food & Beverage Industry

  • Safe for food-grade and sanitary applications where non-toxic, non-contaminating valve materials are required.

• Water Treatment & RO Plants

  • Used in reverse osmosis, demineralization, and water purification systems where resistance to scaling and chemical attack is needed.

• Pulp & Paper Industry

  • Handles aggressive bleaching agents and high-pH media involved in paper processing.

• Oil & Gas and Petrochemical Industry

  • Suitable for low-pressure applications involving hydrocarbons, solvents, or process chemicals.

• Textile and Dyeing Plants

  • Withstands strong dyes and chemicals used in textile finishing processes.

• Biotech & Cosmetic Processing

  • Offers a clean, non-reactive flow path required in biotechnology and cosmetic product manufacturing.

• Acid Handling Systems

  • Excellent for use in pipelines transporting strong acids like HCl, H₂SO₄, and nitric acid due to high chemical compatibility of PTFE and SS 316.

• Laboratory and Pilot Plant Systems

• Reliable in compact systems requiring precision shutoff and minimal contamination risk.

• High-Purity Water Systems

• Used in semiconductor and electronic manufacturing where ultra-pure water and chemical control are critical.
